(CNN) -- Former Secretary of State Hillary Clinton will comment briefly on the debate over potential U.S. military action in Syria when she's at the White House on Monday, according to a Clinton source.
Clinton, whose aide said last week she supported the president's decision to seek congressional authorization for strikes in Syria, is scheduled to appear Monday afternoon for a forum on wildlife trafficking.
Clinton will likely repeat her White House comments during her speech Tuesday night at the National Constitution Center in Philadelphia, the source added.
Also Tuesday night, the president is scheduled to deliver an address on Syria to the public from the White House at 9 p.m. ET.
A potential Democratic contender for president in 2016, Clinton received questions and some criticism for not speaking out after chemical weapons were allegedly used by the regime of President Bashar al-Assad.
On Wednesday, her aide said "Secretary Clinton supports the president's effort to enlist the Congress in pursuing a strong and targeted response to the Assad regime's horrific use of chemical weapons."
In addition to pushing for diplomatic efforts to remove al-Assad from power, Clinton backed a proposal last year to provide weapons to Syrian rebels when she served as secretary of state.
Clinton also issued warnings in January shortly before leaving office about Iran's involvement in Syria, saying the country was supplying al-Assad's regime with military supplies. She urged Iran, as well as Russia, to reconsider their aid to the war-torn country.
Clinton further defended her role as the nation's top diplomat in the situation.
"I've done what was possible to do," she told reporters.
